Biography
William was the illegitimate son of King Henry I of England, and he was from the House of Normandy, a dynasty of Catholic Normans. He held no titles, and he went to court at Gloucester under his half-brother Robert of Gloucester, marrying a woman named Maud. Count Tancred of Lincoln, an opponent of king Stephen of England after his accession in 1135, decided to challenge his rule by pressing William's claim.
